Donít waste your money. I have one and it is a Shark. It is a piece of crap if you ask me.
I have the "Shark" and am not really impressed with the degree to which it cleans my kitchen floor (ceramic tile). It does about as good a job as a quick swipe with a sponge mop but does not give the deep-clean feel that I had hoped for. The floor still needs occasional on-your-knees scrub - as it did with my old sponge mop routine.
I recently bought the latest model of the Shark Steam Pocket Mop, but I bought it online and wasn't able to find one in the stores. I really like the way it handles and it's pretty solidly built. The only thing I didn't like was the price tag (but who would at $100+), but it's done everything it says it will, thus far. I've used mine 3x since getting it at the end of January.
I have the shark from Brndsmart it was on sale and it was the cheapest I have seen them. I think $70 I love it and the best part is my kids argur over who is going to mop the floor! That is worth the $70 right there.
